Remote Terminal Unit for remote control of power grids installed in secondary distribution substations.

The RTU module provides power to system peripherals, can receive digital and analog signals from the field and use them for automatic driving of IMS switches. Measurements and commands are recorded chronologically in a log file.

The module can verify and execute precise commands received and/or send system status information to the central control unit.
The IMS command is performed using dual relay contacts, after the 1/N check and the load impedance check.

Auxiliary ports allow the connection of a wide portfolio of sensors and can drive external loads using relays with voltage-free contacts.

A comprehensive multi-level communication system to and from the central unit ensures a robust transmission channel.

The cybersecurity firmware section and tamper switch ensure a comprehensive degree of protection.
